This smells a lot like a hacker thought because they are exceptional in one field (cybersecurity), they therefore are exceptional in all fields. The result is that information presented in this article is very surface-level, and quite biased.
biased hackers are the best kind of hackers :)
the only thing it takes to be exceptional in most fields is time and effort. there is no secret sauce. There is not something innate that "finance people" have that "computer people" don't, other than a willingness to trudge through boring finance-related crap and vice-versa.
This is all spawned from insecurity that your prestigious degree or whatever can be replicated through independent learning
Being exceptional in cybersecurity is a pretty good indicator that someone will be successful in other fields. A good cybersecurity person will understand that cybersecurity is a mix of technical mastery and the art of understanding human behaviour.
As a much better alternative, I would recommend "debt" by david graeber, which is amazing.
